I've been trying to work out some pattern and realized that the VMs using that much cpu all are Redhat 5.x, the Readhat 6.x doesn't exhibit this kind of high cpu use. (we run only redhat/centos 5.x/6.x on the cluster) I'll take a look to the KSM config. Cheers, Xavier

Ovirt VM Performance abd CPU times
by Xavier Naveira 29 Oct '14

29 Oct '14

Hi, We are migrating our ifrastructure from kvm+libvirt hypervisors to ovirt. Everything is working fine but we're noticing that all the qemu-kvm processes in the hypervisors take a lot of CPU. The typical example is an idle machine, running top from the machine itself it reports cpu use percentages below 10% and loads (with 2 processors) of 0.0x. The process running that machine in the hypervisor rports cpu uses in the order of the 80-100%. Should the values look like this? Why are the idle machines eating up so much CPU time? Thank you.

[QE][ACTION NEEDED] oVirt 3.5.1 RC status
by Sandro Bonazzola 29 Oct '14

29 Oct '14

Hi, We're going to start composing oVirt 3.5.1 RC on *2014-11-25 08:00 UTC* from 3.5 branch. Maintainers: - Please be sure that 3.5 snapshot allow to create VMs before *2014-11-24 15:00 UTC* - Please be sure that no pending patches are going to block the release before *2014-11-24 15:00 UTC* - If any patch must block the RC release please raise the issue as soon as possible. A bug tracker [1] has been opened and shows no open blockers. There are still 193 bugs [2] targeted to 3.5.1. Excluding node and documentation bugs we still have 164 bugs [3] targeted to 3.5.1. Maintainers / Assignee: - Please add the bugs to the tracker if you think that 3.5.1 should not be released without them fixed. - Please update the target to 3.5.2 or later for bugs that won't be in 3.5.1: it will ease gathering the blocking bugs for next releases. - Please fill release notes, the page has been created here [4] Community: - If you're testing oVirt 3.5 nightly snapshot, please add yourself to the test page [5] [1] http://bugzilla.redhat.com/1155170 [2] http://goo.gl/7G0PDV [3] http://goo.gl/6gUbVr [4] http://www.ovirt.org/OVirt_3.5.1_Release_Notes [5] http://www.ovirt.org/Testing/oVirt_3.5.1_Testing -- Sandro Bonazzola Better technology.

Upgrade from 3.5rc to 3.5 final question
by Gianluca Cecchi 29 Oct '14

29 Oct '14

I see this in release notes for 3.5: " If you're using pre-release repo you'll need to re-enable pre release repository: [ovirt-3.5-pre] name=Latest oVirt 3.5 Pre Release #baseurl=http://resources.ovirt.org/pub/ovirt-3.5-pre/rpm/fc$releasever/ mirrorlist= http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-pre-fc$release… enabled=1 skip_if_unavailable=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-ovirt-3.5 and to run: # yum update "ovirt-engine-setup*" # engine-setup " but this leaves me some doubts... I currently have RC3 (or 4, I don't remember exactly). But if I walk through the pre-repo mirror, it seems to me that for example I will get ovirt-engine-backend-3.5.0.1-0.0.master.20141009085636.el6.noarch.rpm while going through 3.5 repo I will get ovirt-engine-backend-3.5.0.1-1.el6.noarch.rpm Are they indeed the same? Can you confirm that if I have a RC release I still have to use -pre repo to update to official 3.5.0? Thanks, Gianluca

migrate from stand alone on FC19 to hosted OK to use CentOS 7?
by Alastair Neil 29 Oct '14

29 Oct '14

I am trying to migrate my old ovirt install which started out at 3.3 standalone engine on FC19 to a hosted engine. I want to use CentOS , however, the postgresql version on 6.5 is old (8.4.20) and I am unable to get a clean restore. The version on FC 19 is 9.2.8, it looks like EL 7 has 9.2.7 (I am hoping the difference in the minor rev will not bite me). I was wondering if there are any issues using EL 7 to host the engine? I know I had seen some reports of issues with 3.5 on EL7 as hosts but was not sure if the engine had any gotchas. Thanks, Alastair

Opened BZ for small mem leak
by Daniel Helgenberger 28 Oct '14

28 Oct '14

Hello Sven and Dan, just FYI I opened a BZ [1] for the small mem leak of VDSM, 300KiB since Sven reported the same thing and it is there (and still is) since a long time now. With some help of us it might be pinpointed; the growth is quite linear. [2] Also, I think the issue might be neglectable in many / most production environments.

MacPoolRanges not working as expected
by Xavier Naveira 28 Oct '14

28 Oct '14

Hi everyone, First of all I'd like to say that we have been using oVirt successfully for more than a year, creating an automated deploy system with help of foreman and puppet. That being said, we're currently facing the first serious problem and we'd appreciate some help. Everything was working fine until we exhausted the default MacPoolRanges. After looking for a solution to the error message we found this document: http://www.ovirt.org/Engine_config_examples#MacPoolRanges Following the instructions on it we executed the following commands: First we found out what our current pool was: # engine-config -g MacPoolRanges MacPoolRanges: 00:1a:4a:24:26:00-00:1a:4a:24:26:ff version: general So we proceeded to expand it: # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:27:ff" # service ovirt-engine restart After this we were able to create new machines but none of them seemed to have network. After some unsuccessful troubleshooting we restored the original pool and instead added a new one: # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:26:ff" # service ovirt-engine restart # engine-config -s "MacPoolRanges=00:1a:4a:24:26:00-00:1a:4a:24:26:ff,00:1a:4a:24:27:00-00:1a:4a:24:27:ff" # service ovirt-engine restart After doing this and test to create a new host everything seemed to work fine. The problem is that after the successful creation of some hosts the original problem where the new hosts didn't seem to have network, reappeared. Trying to narrow down the problem what we've find out so far is: This oVirt environment kickstarts hosts via PXE, when trying to PXE boot a new host, the DHCP process fails (timeout). Tracing the network packets, we are able to see that the virtual host sends the dhcp request, the dhcp server receives it and acknowledges it and it sends the dhcp offer back. The dhcp offer reaches the hypervisor to the vnetxx network interface BUT it doesn't go further and it doesn't reach the virtual host. This behavior is consistent through different hypervisors and vlans, including the ones that have been used/created before the problems appeared. The only pattern that we've been able to identify so far is through issuing the command "brctl showmacs <bridge_name>" This command list the mac addresses for the interfaces connected to the bridge. In the cases where everything works fine the output looks like this: port no mac addr is local? ageing timer 2 00:1a:4a:24:27:e0 no 0.01 2 fe:1a:4a:24:27:e0 yes 0.00 The virtual host MAC address begins with "00" and it has a corresponding address beginning with "fe" which is assigned to the "vnetxx" interface in the hypervisor. In the cases where the virtual host doesn't get the dhcp answers the output of "brctl showmacs <bridge_name>" is: port no mac addr is local? ageing timer 6 fe:1a:4a:24:27:a0 yes 0.00 This is, the actual virtual host's MAC address is missing from the bridge. We haven't been able to find a detailed explanation on how the network internals of oVirt should work but hopefully someone in this list can point us to the right resource. Thank you. Xavier.

oVirt 3.5 on RHEL 6.6 hyperv enabled breaks Windows VMs
by Charles Gruener 28 Oct '14

28 Oct '14

https://bugzilla.redhat.com/show_bug.cgi?id=1110305 This enabled the hv_relaxed flag on all my Windows VMs, causing them to no longer boot. The same thing would happen if I simply booted from the Windows install media. I would get a screen with a stop error: Your PC needs to restart. Please hold down the power button. Error Code: 0x0000001E Parameters: 0xFFFFFFFFC0000096 0xFFFFF802C4044EA4 0x00000000000000000 0x00000000000000000 I created a file called /etc/ovirt-engine/osinfo.conf.d/01-windows.properties that had one line: os.windows_xp.devices.hyperv.enabled.value = false I restarted ovirt-engine and now I can start my Windows VMs. Why does this occur? Is it because I upgraded from 3.4 to 3.5? Is there something else I'm doing wrong? I would like to not need this workaround. Thanks. Charles

Well, in fact have got something to work now! Left ovirtmgmt and em1 alone but ran: $ ovs-vsctl add-br ovsbr0 $ ip link add name veth0 type veth peer name veth1 $ brctl addif ovirtmgmt veth0 $ ovs-vsctl add-port ovsbr veth1 $ ip add add XXX.XXX.XXX.XXX/29 dev veth1 $ ip link set veth0 up && ip link set veth1 up and now veth1 is responding as-well as veth0. ovs-vsctl show 08554d11-3ba7-4303-b9d5-6a09f23c9057 Bridge "ovsbr0" Port "veth1" Interface "veth1" Port "ovsbr0" Interface "ovsbr0" type: internal so what I think should do now is create a custom parameter on the Engine Manager that allows one to define an OVS bridge name and VLAN so when a virtual guest is created it can be assigned to the new bridge; with the use of a custom hook.

So at that point you have network running. If you then try to add that to the OVS stack your networking stop :( I tried to add it as a port using ovs-vsctl add-port ovsbr0 ovirtmgmt which is accepted but then networking stops. As soon as I remove again networking comes back to life.

You could just make a hook script that runs an after_network_setup hook that does the ovs-vsctl for you ;-) Here you can see the presentation I gave last February at devconf about extending with configurators and hooks. http://blog.antoni.me/devconf14/#/8/1 I linked directly to a before_network_setup hook sample, because it works just like the after_network_setup hook. Instead of logging to systemd, just add that if 'remove' is not in data and network == 'ovirtmgmt', it adds the network bridge to the vswitch with python's subprocess.call or subprocess.check_output. You can send it if you want me to take a look ;-) PS: It is possible to write the hooks in bash, c, perl, etc. But we only have the convenience read_json methods and such for python. If you wanted to, you could have a simple bash hook that just checked if there was an ovirtmgmt bridge and it would add it doing ovs-vsctl in the before_vdsm_start hooking point. That would have the drawback that changing the ovirtmgmt bridge with oVirt UI would leave it disconnected again. > > Thanks, Phil > > ----- Original Message ----- > From: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > To: "Phil Daws" <uxbod(a)splatnix.net> > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > Sent: Monday, 27 October, 2014 9:56:38 AM > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > ----- Original Message ----- > > From: "Phil Daws" <uxbod(a)splatnix.net> > > To: "Antoni Segura Puimedon" <asegurap(a)redhat.com> > > Cc: "Dan Kenigsberg" <danken(a)redhat.com>, users(a)ovirt.org > > Sent: Monday, October 27, 2014 10:37:18 AM > > Subject: Re: [ovirt-users] oVirt 3.5 & NAT > > > > That is what I tried but oVirt appears to overwrite the bridge information > > on > > boot :( Thanks, Phil > > But before rebooting, does it work as you intended?

On a fedora 19 system where I had 3.4.4 all-in-one, I was able to upgrade to 3.5. vdsm part had problems I was able to solve reinstalling host from the webadmin gui Steps were: - follow instructions for engine part --> ok - verify connectivity of engine via new webadmin - put host into maintenance - stop vdsmd service - yum update vdsm part and all other packages related to ovirt When trying to start vdsm again I got [root@tekkaman vdsm]# systemctl status vdsmd vdsmd.service - Virtual Desktop Server Manager Loaded: loaded (/usr/lib/systemd/system/vdsmd.service; enabled) Active: failed (Result: start-limit) since Sat 2014-10-25 16:01:29 CEST; 2min 54s ago Process: 14448 ExecStartPre=/usr/libexec/vdsm/vdsmd_init_common.sh --pre-start (code=exited, status=1/FAILURE) Oct 25 16:01:29 tekkaman.localdomain.local systemd[1]: Failed to start Virtual Desktop Server Manager.

Nevertheless a host reinstall from webadmin gui seemed to fix the problem and after that it was able to start vdsm ad host part. I was also able to upgrade DC/Cluster from 3.4 to 3.5 version. Now that I'm on 3.5 next days I'll try to pass from F19 to F20... we'll see Gianluca

oVirt 3.5 & NAT
by Phil Daws 27 Oct '14

27 Oct '14

Hello All! Am really enjoying experimenting with oVirt but have come across a question; how does one enable NAT for a VM ? Would like my guests to be able to update their software by bridging the host public IP. I could not see anything in the WUI to allow this ? Thanks, Phil

Deleting large snapshots blocks the whole cluster

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --WvJXSM0TULQwmuWL0sQNHhbN8U0LDFtiQ Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi, we have some really large snapshots left from a migration. Since our store is almost full now we have to delete them now. Some snapshots are around 1TB already. The last time we tried to delete a ~500GB snapshot the delete task blocked the whole diskstore's IO and the whole cluster and all hosts became unavailable. Is there a way to delete large snapshots in a "humane" way that will not block everything?

Problem installing hosted engine on CentOS 7 host
by Justin Clacherty 27 Oct '14

27 Oct '14

Hi, I'm just trying to set up ovirt 3.5 for testing and am unable to get hosted engine installed. The problem appears to be something to do with multipath iscsi setup. I run 'hosted-engine --deploy' and answer all the questions. See the config preview below. --== CONFIGURATION PREVIEW ==-- Engine FQDN : ovirt.domain.local Bridge name : ovirtmgmt SSH daemon port : 22 Firewall manager : iptables Gateway address : 192.168.42.254 Host name for web application : hosted_engine iSCSI Target Name : iqn.2014-10.storage.domain.san0:iscsi0 iSCSI Portal port : 3260 Host ID : 1 iSCSI LUN ID : 0 Image size GB : 25 iSCSI Portal IP Address : 10.50.0.200 iSCSI Portal user : myuser Console type : vnc Memory size MB : 4096 MAC address : 00:16:3e:23:b4:c2 Boot type : cdrom Number of CPUs : 2 ISO image (for cdrom boot) : /tmp/CentOS-7.0-1406-x86_64-DVD.iso CPU Type : model_Nehalem At the iscsi target question it shows both target names (for each of the multipath options) but you only seem to be able to choose one. After confirming the settings above I get the following. [ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf' [ INFO ] Stage: Transaction setup [ INFO ] Stage: Misc configuration [ INFO ] Stage: Package installation [ INFO ] Stage: Misc configuration [ INFO ] Configuring libvirt [ INFO ] Configuring VDSM [ INFO ] Starting vdsmd [ INFO ] Waiting for VDSM hardware info [ INFO ] Creating Volume Group [ ERROR ] Failed to execute stage 'Misc configuration': Failed to initialize physical device: ("['/dev/mapper/36001405fbaac4f30dd647b083c6a0116']",) [ INFO ] Stage: Clean up [ INFO ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf' [ INFO ] Answer file '/etc/ovirt-hosted-engine/answers.conf' has been updated [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination The /dev/mapper leads me to believe it's a multipath issue. I noticed this Bugzilla entry when looking into the issue so it appears at least one other person is experiencing the same issue. https://bugzilla.redhat.com/show_bug.cgi?id=1154353 Cheers, Justin.

Import FC Storage as iSCSI
by Raul Laansoo 27 Oct '14

27 Oct '14

Hello. I have created an FC Storage Domain and made snapshots of all LUNs on the SAN. Now I want to use those snapshots on another Data Center over iSCSI connection to test recovery. I can import the domain, but the domains Storage Type is FC and I can't attach it to host. Is it possible to change domain type to iSCSI or some other way to import storage domain. Thank you. Raul

Re: [ovirt-users] vmware type functionality

On 24/10/14 15:31, Bill Dossett wrote: > Hi, Thanks for that. I understand I can see that, but in vmware we sometimes get orphaned VMs that the portal loses for one reason or another and you have to register the with the system again. Or If I move to some new storage and have to copy the VMs to the new storage and then reregister them with a new storage domain - I normally browse the datastore in VMware for the vmx config file and then I can reregister it... But maybe Ovirt when you present a new storage domain just sees the VMs and you don't have to register? I haven't been down this route - well I sort of was, but also if I have VMs on a storage domain and say want to connect it to another data center, can I non-destructively do that? Sorry, kind of a steep learing curve I've been on for the last couple of weeks. You should keep the users list cc'ed so everybody with the same questions can find the answers too :) Well I never have seen "lost" vms in ovirt, but if you want to move vms between storage domains afaik the only way to currently do so is to export a vm from a data domain to an export domain and than import from this export domain to another data domain. export domains are basically nfs storage systems, so you want to make sure your firewall and selinux settings are correct. it's also possible to detach export domains, tar them and then untar them in another ovirt einvironment and import this whole export domain (use the "-S" flag if you have "sparse" vms!). this should also be possible for data domains somehow: http://www.ovirt.org/Features/ImportStorageDomain but I didn't try this myself yet, so I don't know if this really works yet (new features tend to need a point release until they are matured enough ;) ) HTH -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
